MCP-1 involvement in glial differentiation of neuroprogenitor cells through APP signaling.

ABSTRACT: Previously it has been reported that neural stem cells undergoing apoptotic stress have increased levels of amyloid precursor protein (APP) and increased APP expression results in glial differentiation. APP activity was also shown to be required for staurosporine-induced glial differentiation of neuroprogenitor cells. Monocyte chemoattractant protein-1 (MCP-1) is a chemokine that is expressed early during inflammation. The binding of MCP-1 to its chemokine receptor induces expression of novel transcription factor MCP-1-induced protein (MCPIP). MCPIP expression subsequently leads to cell death. Previous studies have shown that pro-apoptotic factors have the ability to induce neural differentiation. Therefore, we investigated if MCPIP expression leads to differentiation of NT2 neuroprogenito
